Hi to you too,

Neither in PL/I nor in any other language your can read and write AT THE SAME TIME icon_wink.gif You probably mean input-output or update mode. And yes someone can help you; you yourself and the manual. At this site there's a manual (see toplever menue) which explains it all. If you have any problems after reading the manual (search for 'OPEN FILE') get back to us.
